我正在嘗試造一個(gè)從數(shù)組中隨機(jī)選擇項(xiàng)目?jī)纱蔚木渥?。第一個(gè)選擇的項(xiàng)目暫時(shí)從數(shù)組中刪除，因此不能再次選擇，然后第二個(gè)項(xiàng)目也被隨機(jī)選擇并添加到句子中。然后，為了重置它以便稍后可以再次執(zhí)行此操作，我嘗試將第一個(gè)選擇的項(xiàng)目添加回其初始數(shù)組。問(wèn)題是，當(dāng)我這樣做時(shí)，chosenWord1 在句子中顯示為我希望的字符串，但 chosenWord2 顯示的是索引號(hào)。array = ["word","another word", "yet another word"];/* put a random word from the array in its own value and then remove it from the array so it can't be chosen in next step */let chosenWord1 = array.splice(Math.random() * array.length, 1)[0];/* pick another random word from the same, altered array */let chosenWord2 = Math.floor(Math.random() * array.length);/* a function that puts a sentence on the webpage concatenating the strings from chosenWord1 and chosenWord2 goes here. then... *//* add back the previously removed word so this process can repeat again with the same items in the array as there was before anything was done to it */array.splice(1,0,chosenWord1);另外，如果有一些更明智的方法可以構(gòu)建它，請(qǐng)告訴我。我對(duì)此還是很陌生。
